Starter Problem

Can anyone help me with a starting problem with an older SL 700. Pressing the starter button with a new battery installed produces a "whirring" sound which I assume is the starter motor. However, the engine does not turn over. I assume that some sort of gear in the starter motor should be engaging with the engine to turn it over. I am fairly handy and would like to fix this myself. Does this sound like a project that a do-it-yourselfer can handle? Can anyone describe what I must do to make the repair? Thanks

I was searching the site for a starter part number but do I just need the Bendix?

You press Start, and you can hear the starter motor spinning, but the engine does not crank - correct?

Then the Bendix is the problem.

You will need to remove the flywheel to replace the Bendix. When you remove the flywheel cover, you will be able to see if the flywheel is still in position with all its teeth. If the flywheel is good, then the Bendix is the culprit.
